Please refer to FIG. 19 to FIG. 22 synchronously. These diagrams show the use state of the pickup truck bucket space covering device 1 on the pickup truck 2 . On the whole, when the left driving wheel set 21 and the right driving wheel set 22 synchronously push the ㄇ-shaped tailgate frame 131 to move toward the closing structure 14, the ㄇ-shaped tailgate frame 131 pushes the sliding wheel plates on both sides to tighten the closing structure. A usable space covered by the combination structure 14, these ㄇ-shaped adjustment frames, the tailgate assembly 13 and the base plate assembly 10 is shown in FIG. 21 . When the left driving wheel set 21 and the right driving wheel set 22 synchronously push the ㄇ-shaped tailgate frame 131 to move away from the closed structure 14, the ㄇ-shaped tailgate frame 131 pulls and stretches the sliding wheel plates on both sides sequentially to expand the use space, as shown in the figure 21 is shown. In addition, when the tailgate assembly 13 is in any position, its tailgate 132 can be opened to use the use space, as shown in FIG. 20 and FIG. 22 . Certainly, besides the box space of the pickup truck, this usable space is an additional space, and its size can be adjusted according to the needs of users.
